what do i think of Dr Hvac? i think they are a load of ***, from the first day they installed my ductless heat and air we had nothing but problems. especially the air conditioning factor constantly freezing up. three different tech guys came out on multiple occasions, but none of them knew what the other was doing. each one had different explanations and problems but none were the answer to fixing the problem. now we are told the labor warranty is up and its 102$ an hour to fix a problem they NEVER fixed to begin with. so now we are stuck with a 4,000$ paper weight. if you are thinking about going with this company i strongly suggest finding someone else maybe you will end up with a product that works all they care about is taking the money not installing a good working product.
